This article covers Lian Li UNI ファン SL-Infinity UF-SLIN120-3B.

Overview

The Lian Li UNI Fan SL-Infinity UF-SLIN120-3B is a 120mm case fan triple pack that combines the design language of the original UNI FAN SL and AL series. It features a multi-layer infinity mirror effect that delivers clear RGB illumination from any angle. With a maximum speed of 1800 RPM, airflow of 61.3 CFM, and noise level as low as 15 dBA, it strikes an excellent balance between cooling performance and quiet operation. The black frame and clear blades offer a sleek, modern aesthetic suitable for any build theme.

Compatibility Guide

These fans use a standard 120mm mounting pattern with a thickness of 25mm, ensuring compatibility with most ATX, Micro-ATX, and Mini-ITX cases. They connect via a 3-pin power connector; speed control is achieved through voltage regulation rather than PWM. For RGB control, the included UNI HUB or a compatible Lian Li controller is recommended. Each fan draws about 5W at 12V. While direct connection to a motherboard 3-pin ARGB header is possible, the full infinity effect and synchronized lighting across multiple fans are best achieved with the hub.

Product Info

Released in late 2022, the UF-SLIN120-3B is positioned as a mid-range premium fan kit. The package includes three fans, mounting screws, and a UNI HUB controller. Retail pricing is around ¥19,000 in Japan. The fans utilize fluid dynamic bearings (FDB) for longevity and quiet operation. LED lighting features a unique infinity mirror design that creates a layered, depth-filled effect. Warranty varies by retailer but typically covers one to two years.

Best Use Cases

Gamers seeking distinctive RGB aesthetics: The infinity mirror effect provides a visually striking lighting experience that stands out. Quiet PC builders: At only 15 dBA, these fans are nearly inaudible in typical desktop usage. * Enthusiasts building a coordinated system: The UNI series allows matching case fans and radiator fans for a uniform look.

Things to Consider

The 3-pin connector means these fans do not support PWM speed control; they rely on voltage regulation, which may not be as precise. For full RGB control and the infinity effect, the UNI HUB is required – connecting directly to a motherboard header may limit lighting patterns. Competitors like the Noctua NF-A12x25 offer better airflow per noise, while Corsair LL120 provides more customizable RGB. However, the Lian Li SL-Infinity's daisy-chain connector reduces cable clutter significantly. Ensure your case supports the fan count and that CPU cooler clearance is sufficient when installing these fans.
